Question

In a unilocular ovary the ovules develop from all over the wall. The placentation is

• A. Superficial
• B. Marginal
• C. Free central
• D. Parietal

Answer 1

The correct option is A Superficial

A. In superficial placentation, the ovules develop over the entire inner surface of the wall of the ovary. The ovary is multicarpellary. It is seen in Nympheae.

B. Marginal placentation- the ovules develop on the ridge formed by the placenta over the ventral suture.

C. Free central- the ovules are attached to the extension of the floral axis.

D. Parietal placentation- the ovules develop on two opposite lines of the wall of the ovary.

Hence, the correct answer is 'Superficial'.
